Spermidine makes me feel good After using Spermidine along with NAD+, I have not only noticed increased daily energy, but also significant improved hair and nail quality. I’m very happy with it, and will definitely continue take it as long as I have the possibility.

Spermidine. I cannot express the difference in my general well-being since I added Spemidine to my daily kefir smoothie. My hair has grown, nails are stronger but the most significant change is the quality of my sleep. I sleep well and deeply. It’s incredible.

Love It I'm very happy with spermidine. My most significant improvement is my bald spot is almost gone. This is in less than six months! I haven't experienced the sleep improvement but I already have healthy sleeping habits so no surprise there. I absolutely love the product and highly recommend it.

A big improvement in cognition After only a month of using Primeadine, I’ve noticed that I’ve been recalling ideas a lot better, and my ability to put abstract ideas into words has improved. Overall, my cognition has improved significantly.

Better sleep, hair, nails I've been using Primeadine for over 3 months now. Almost instantly, I noticed an improvement in my sleep. I take it before bed time and my sleep scores (measured on my Sleep Cycle app in my iPhone) have increased from the 70's to the high 80s / low 90s. I've noticed that I have much more vivid dreams and I wake up feeling more rested. Additionally, my hair loss has reduced and I can see a lot more new growth - even my eye lashes are thicker! My nail are also stronger and more glossy.
